Grandma granted remote access and now laptop is taken over

[Mjett15]

My grandma had a guy work on her laptop remotely and since then has had countless remote sessions. Odd files and folders saved in various places and users being added, deleted, enabled/disabled including the build in administrator etc. I completely (or at least I thought it was completely) wiped the os from the disk and installed Windows 10 Home from my own recovery flash drive. Once installation finished I looked around and still found bookmarks (although no account was signed in to the browser to sync bookmarks from) most being to sites supposedly HP help sites as well as yahoo search and whatnot. Also, there are still external IP addresses creating/enumerating/etc new and existing users (mind you, the only user that should be on it is the one I created for my grandma using a newly created Microsoft Account at the "clean" install I did). Somehow, the computer is linked to a workgroup and domain which also has external IP addresses involved. Even though her account should be the administrator user it's permissions have been revoked for most of the system/administrator settings and files and folders. I have run Rkill, and RogueKiller for 64bit is running now, so far, but I have yet to see if they've done any good.

Hello @Mjett15 and

 

Please run the following steps and post back the logs as an attachment when ready. We'll see what we can find.

STEP 01

• If you're already running Malwarebytes 3 then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• If you don't have Malwarebytes 3 installed yet please download it from here and install it.
• Once installed then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
• Once the scan is completed click on the Export Summary button and save the file as a Text file to your desktop or other location you can find, and attach that log on your next reply.
• If Malwarebytes won't run then please skip to the next step and let me know on your next reply.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

• Right-click on the program and select Run as Administrator to start the tool.
• Accept the Terms of use.
• Wait until the database is updated.
• Click Scan.
• When finished, please click Clean.
• Your PC should reboot now if any items were found.
• After reboot, a log file will be opened. Copy its content into your next reply.

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

• Double-click to run it. When the tool opens, click Yes to disclaimer.
• Press the Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here.
• Please attach the Additions.txt log to your reply as well.

 

Thanks

Ron

Thank you for your help on this matter. Before I reinstalled the OS my grandma had TeamViewer already installed as well as LogMeIn and various other remote access software. She said someone would close out windows randomly and whatnot when she would try to use the computer and she even got a piece of paper taped over the webcam because she said the guy was trying to access her camera. I think I ran the scans correctly. I wasn't surprised that the Malwarebytes scan found 305 threats, I just could never wipe any out before. Thanks again

Also, just started doing it after the scans, when I right click on the desktop and click new (was trying to create a folder to store the scan reports in) it freezez for a second and then says "explorer.exe - Application Error. The instruction at 0x00007FFC4E0058A6 referenced memory at 0x0000000000000000. The memory could not be read. Click OK to terminate the program."

Overall the logs look pretty good now. Please go ahead and run the following.

 

Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

fixlist.txt

Thanks

Ron

I can't get into Activation in settings to enter my windows 10 pro product key to upgrade from home, and it is still doing the thing Mentioned in my last reply.

I'm probably not going to be able to help you much with the Upgrade issue of Windows, but please run the script I provided and we'll see if that helps
